Abstract
(EN)
The present invention relates to a method whereby a station transmits ACK information, the method comprising: receiving, from an access point (AP), TDD allocation information in one service period (SP), wherein, if the one SP includes one or more first time units and if one first time unit includes one or more second time units, the TDD allocation information includes information about all of the second time units included in the one SP; and transmitting, to the AP, the ACK information in one or more second time units, determined on the basis of the TDD allocation information, within the one SP.
(FR)
La présente invention concerne un procédé par lequel une station transmet des informations d'accusé de réception (ACK), le procédé consistant à : recevoir, d'un point d'accès (AP), des informations d'attribution de TDD dans une période de service (SP) ; si la SP comprend une ou plusieurs premières unités de temps et si une première unité de temps comprend une ou plusieurs secondes unités de temps, les informations d'attribution de TDD comprennent des informations concernant toutes les secondes unités de temps incluses dans la SP ; et à transmettre, à l'AP, les informations ACK dans une ou plusieurs secondes unités de temps, déterminées sur la base des informations d'attribution de TDD, à l'intérieur d'une SP.
(KO)
액세스 포인트(AP)로부터 하나의 서비스 구간(SP) 내 TDD 할당 정보를 수신하되, 하나의 SP가 하나 이상의 제1 단위 시간을 포함하고, 하나의 제1 단위 시간이 하나 이상의 제2 단위 시간을 포함하는 경우, TDD 할당 정보는 하나의 SP에 포함된 모든 제2 단위 시간에 대한 정보를 포함하고, 하나의 SP 이내에 TDD 할당 정보에 기초하여 결정되는 하나 이상의 제2 단위 시간에서 ACK 정보를 AP로 전송하는 것을 포함하는 스테이션의 ACK 정보 전송 방법에 관한 것이다.
